In November 2005, Honda filed a statutory recall with Japan's Ministry of Land, Infrastructure, Transport and Tourism (MLIT) concerning the Continuously Variable Transmission, covering the Odyssey, Stream. The filing affects 98,768 vehicles manufactured between October 2003 and October 28, 2005.
Overview
| MLIT filing number | 1115640 |
|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | November 24, 2005 |
| Manufacturer(s) | Honda |
| Component | Continuously Variable Transmission |
| Production period | October 2003 — October 28, 2005 |
| Vehicles affected | 98,768 units |
Filing in context
The Continuously Variable Transmission is the most frequently cited component category in this archive, appearing in 8 of its 4,890 filings. This filing is one of 22 Honda notifications from 2005 in this archive. For scale, 471 of the 4,890 filings in this archive report a larger number of affected vehicles; the vehicles involved here were manufactured over a span of about 2 years.
Defect
The control unit software for the continuously variable transmission (CVT) is incorrect, causing the CVT oil pump to generate excessive hydraulic pressure at low engine speeds. This causes the pump vane sliding surfaces to wear prematurely. Continued use leads to abnormal vane wear, preventing the system from maintaining adequate hydraulic pressure. In the worst case, the oil pump may fail and the vehicle may become inoperable.
Corrective action
On all vehicles, reprogram the CVT control unit with corrected software and replace the transmission oil with a high wear-resistance grade. Additionally, inspect the CVT hydraulic control sensor output value; if it falls outside the specified range, replace the CVT with a new unit.

状況
無段変速機用電子制御装置のプログラムが不適切なため、無段変速機へ油圧を供給するオイルポンプが低回転時に供給油圧が高くなる場合があり、オイルポンプベーン（羽根）摺動部が早期に磨耗するものがある。そのため、そのまま使用を続けると、ベーンが異常磨耗し、適切な油圧が確保できなくなり、最悪の場合、オイルポンプが破損して走行不能となるおそれがある。
改善措置
全車両、無段変速機用電子制御装置のプログラムを対策した内容に書換えるとともに、耐磨耗性の良いミッションオイルに交換する。また、無段変速機の制御油圧センサ出力値を点検し、点検基準を外れるものは無段変速機を新品と交換する。
